hey guys, i'm on my second grow, ebb e flow diy with clay plebes as media witch I am already looking to get rid of lol.
thinking about adapting my setup witch consist of a 40L reservoir under a flooding table, thinking about getting something that i can turn into a top reservoir that has a lid, so i would put my clones that comes from my cloner with roots already hanging there on holes that i would make to fit the net pots.
i grow sog, usually 10 to 15 single sticks as i have a small grow area and this gives me the best return.
thinking about not using an air pump to easy with the heat and have a constant flow going thru a waterfall on the return pipe.
any feed back is much appreciated.

a sheet of plywood over your rez will be enough to drill holes in to accommodate net pots.
the top reservoir is easy to work around, more worried about the oxygen to the roots, forgot to mention my water temps range from 72-75, not looking to add any more heat, that's why i want to get way without using an air pump, my current water pum is a 1000L/h one, would like to know how much heat it could bring in to the solution also if anyone with more experience with circulating systems would have an ideia.

Instead of using an air pump use a wave maker in the res it creates very little to no heat at all. I was using a small pond pump in my res to keep the solution mixed and it would heat up the water so switched to a wave maker and if I forget to turn it off my temps don’t rise at all

what would happen if we cut off your air pump??..... righhhhttttt, lower temp another way.
the water is oxygenated thru the breaking of water tension by the bubbles, not from the bubbles being in the water, that's why a wave maker would also work as the other guy said, going to give some tough to it, thinking i would need one for the top and one for the bot.
if the waterfall is enough i think it would be better, less stuff to worry about.

i understand oxygen. didnt know wave maker was an option, thats why, i only reply to information before me, not ffuture posts after know what i mean?

If you have a waterfall setup you don’t need an air pump or a wave maker just the waterfall is enough to oxygenate the water.

the wave maker option was not meant to dismiss your post, it was more of a reply to the other post
in this setup there would be two pints where the water tension would be breaking, in the waterfall and in the upflow by the pump being higher than the water level of the top reservoir, just trying to make sure if it would be enough.
someone told me a good option cold be having the air pump anyways and making it draw air from the ac outlet so maybe ai could even bring the temps down a bit more.
i don't have any experience with air pumps but everywhere i look people are kinda worried about the amount of heat it integrates into the system, left me a impression it would be more than a water pump of similar power running 24/7

Heat from airpumps? We must live in two different realities. The amount of aeration needed to saturate a solution is less than people may think. More bubbles going through the solution might be contra productive since it will affect pH by introducing CO2. You also need a larger air pump creating more heat.

I use small ass pumps in my big reservoirs. If I get away with a tiny Marina 75 air pump for 30 gallons you can do the same, that won't affect temps at all. With your design you won't need any air stones since you can run waterfalls.

I have no idea how much heat an air pump would generate lol, i was looking into pumps with around 15L/min, I've read that the recommended is 1L/min of air per gallon of water in the system, i'm estimating the total volume of water in the system to be around 60L or 15.8 gallons
every board i look people worry about the heat with air pumps
